On the Fermentation Type and Ecology of Anaerobic Hydrogenogenic Bacteria

Li Baikun (Northern Jiaotong University,Beijing,100044)  
On the basis of the anaerobic treatment of high strength wastewater,batch anaerobic culture is employed to research the hydrogenogenic bacteria.According to the research on niche,ecological factors and coordination among bacterium,it indicates that the change of O 2,pH,COD concentration may lead to the change of fermentation type.Pure hydrogen producing bacteria were isolated from anaerobic fermentation sludge.By using refined sugar as substrate,the largest H 2 production was 84.4 ml H 2/g bacteria·h.The comparison on hydrogen producing ability between sludge mixed and pure bacteria shows that coordination among bacteria plays a major role in hydrogen producing.The optimal ecological control factors of ethanol type fermentation is put forward.
